5x+2y=22. -2x+6y=3 What is the X coordinate of the solution. Round to the nearest tenth

just olya [345]

Multiply first example by 3 and subtract by second example, you will get the following:

3*(5x + 2y) = 3*22 => 3*5x + 3*2y = 66 => 15x + 6y = 66
now subtraction:
(15x + 6y) - (-2x + 6y) = 66 - 3
15x + 6y + 2x - 6y = 63
15x + 2x + 6y - 6y = 63
17x = 63
x = 63/17 ≈ 3.705..... and as it says to round to the nearest tenth our answer would be: x = 3.7

Which answer describes the type of sequence? 3,4,5,6,...

In-s [12.5K]

Answer:

Arithmetic Sequence

Step-by-step explanation:

we know that

In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, and this constant is called the common difference

we have

$3,4,5,6,...$

Let

$a_1=3\\a_2=4\\a_3=5\\a_4=6$

$a_2-a_1=4-3=1$

$a_3-a_2=5-4=1$

$a_4-a_3=6-5=1$

the difference between one term and the next is a constant

The common difference is equal to 1

This is an Arithmetic Sequence

What is the greatest common factors of 120 and 6

horrorfan [7]

If we want to know the greatest common factor, we should ask: is one of the numbers divisible by the other? if yes, then the smaller number will be the answer!

let's try:

$\frac{120}{6} = \frac{60}{3} =20$

so, yes!
6 is the greatest common factor of the two:)

The average daily temperature, t, in degrees fahrenheit for a city as a function of the month of the year, m, can be modeled by

Vikentia [17]

The answer will be t = $sin((m.\frac{\pi}{6})+55)$ average daily temperature, t, in degrees Fahrenheit for a city as a function of the month of the year.

<h3>What is temperature?</h3>

Temperature is the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

<h3>TO SOLVE:</h3>

$35cos(\frac{\pi}{6(m+3)}+55)\\\\35 cos(\frac{\pi m}{6} + 55 + \frac{\pi}{2})\\$

suppose $x = m.\frac{\pi}{6}+55$ and $\frac{\pi}{2} = 90$ degree

We know, cos(x+90°) = - sin(X)

⇒ $cos((m.\frac{\pi}{6})+55+90degree)$ degree = - $sin((m.\frac{\pi}{6})+55)$

⇒ t = $sin((m.\frac{\pi}{6})+55)$

Hence the answer will be t = $sin((m.\frac{\pi}{6})+55)$ average daily temperature, t, in degrees Fahrenheit for a city as a function of the month of the year.
